16 mm hyperdense mass at the level of foramen of Monro. Mild hydrocephalus.
Incidental cavum septum pellucidum et vergae
T1 hyperintense, intermediate T2 cyst at the foramen Monroe. Signal characteristics indicate proteinaceous contents in this case.

A smaller, non obstructive colloid cyst is now present. Note surgical defect in the corpus callosum post transcallosal resection.
